What Is a Certificate of Analysis?
A Certificate of Analysis, often shortened to COA, is a laboratory document used to report analytical testing for a specific sample. For research compounds, a COA may include compound identity, purity percentage, analytical method, testing date and sample reference information.
Astra Labs uses this Certificates of Analysis hub to make available verification records easy to access from one central page. This helps customers review external testing information directly, rather than relying only on screenshots, product descriptions or unsupported quality claims.
Updated 2026 Janoshik verification links have now been added for selected products, including Retatrutide 10mg, Retatrutide 20mg, GHK-Cu 50mg, MOTS-C 40mg, Semax 10mg and Selank 10mg.
Why Direct Janoshik Verification Links Matter
Direct Janoshik verification links are stronger than static screenshots because they allow customers to open the external testing record and review the available information themselves. This is an important trust signal for research compound suppliers.
Astra Labs will continue adding available Certificates of Analysis records as product testing information becomes available. Not every product will always have the same documentation status, so customers should review the individual COA links and product pages before ordering.
This approach supports transparency, buyer confidence and AI-search readability by making testing information easy to understand, easy to access and clearly connected to the relevant research compound category.
